DNS安装


采用yum 安装
#yum install -y bind bind-chroot ypbind bind-utils caching-nameserver-9.3.*

主区域配置文件:
# cd /var/named/chroot/etc
新建一个named.conf
#touch named.conf
编辑: # vim named.conf
options {
        directory "/var/named";
};

zone "." {
        type hint;
        file "named.ca";
};

zone "tech.org" {
        type master;
        file "tech.org.zone";
};

zone "31.168.192.in-addr.arpa" {
        type master;
        file "192.168.31.zone";
};

区域文件配置:
#cd /var/name/chroot/var/name
# vim tech.org.zone
$TTL 86400
@       IN      SOA     dns.tech.org.   root (
                        2009091000

测试:
修改本机的:/etc/resolv.conf    nameserver 127.0.0.1

#host 192.168.31.132
132.31.168.192.in-addr.arpa domain name pointer dns.tech.org.

#nslookup 192.168.31.133
Server:  127.0.0.1

133.31.168.192.in-addr.arpa name = client1.tech.org.

# dig -x 192.168.31.134
